Céphalothorax (PI. IV, fig. 12a). — No eyes or ocular spots are found. The 

 céphalothorax is a little broader behind than it is long and tapers towards the 

 front margin, which is only one third of the hindmost in breadth ; the lateral out- 

 line of the céphalothorax is in front of the first groove moderately concave, so that 

 a rather long cucuUus is found. The two transverse grooves are prominent and 

 very broad, so that their real nature as articulate membranes is unmistakeable; 

 they are moderately curved backwards in the middle and distinctly widened out 

 towards the lateral margin. The skin is everywhere beset with large, more or 

 less pointed granules and with distinctly clavate hairs, which are enlarged towards 

 their tip and here about half as broad as long; six hairs are placed along front 

 margin and the head possesses in addition to those about 20 placed without any 

 proper order; the first thoracic tergite has its hairs arranged in two rows, while 

 the second has a similar median transverse row. 



Abdomen (PI. IV, fig. 12 a). — The abdomen, which is distinctly longer than 

 broad, is almost egg-shaped, having its greatest breadth somewhat behind the middle. 

 It is moderately curved from right to left, or perhaps more correctly from both 

 sides raised towards the middle, so that a low longitudinal keel is found, but 

 distinctly curved from the base towards the apex, so that the last four (VII — X) are 

 indistinctly seen from above and the eleventh not at all. The second to the ninth 

 tergites are divided by a not very distinct longitudinal line into two halves, which 

 has the anlerio-interior corner rounded and the posterio-interior produced into a 

 point, establishing an obtuse angle open in front with that of the other side. The 

 tenth tergite is, observed from above, very short, but, when observed from behind, 

 it is of a considerable length ; the eleventh tergite is only visible from below, is 

 very short and distinctly shorter than the corresponding sternite, from which it is 

 separated by a distinct articulate membrane. The abdomen is above granular 

 everywhere with distinct granules, which are flatter and generally more densely 

 placed than those of the céphalothorax. The not very well limited sclerites are 

 more distinctly granular than the rest, especially a transverse darker band through 

 the middle. The distinctly clavate hairs, which are articulated within smooth 

 spots surrounded by a circular row of granules, are arranged in a single transverse 

 row, numbering from 14—20 hairs; the eleventh tergite has only ten hairs. 



The eleventh sternite, which almost completely surrounds the anus, as the 

 corresponding tergite is much shorter, bears a few rather slender hairs. The pre- 

 ceding six (V — X) sternites, which are of almost equal breadth, but increase in 

 length towards the last, are divided by a longitudinal line, and their granulation 

 is most distinct in a transverse band along the front margin. The sternites bear 

 about 16 hairs placed in a transverse row and the sixth to the ninth have in 

 addition to these about 30 yellow spots along anterior margin, in which hairs are 

 perhaps articulated. In front of the fifth sternite a long plate with a short divided 

 sclerite is found, as well as an undivided very short chitinous piece (third sclerite?),
